* AssPull: Most of the second half of Episode 10. [=ThornBrain=] admitted that he [[http://themidnightfrogs.wikia.com/wiki/Sgt_Frog_Abridged_-_Episode_10#Additional_Trivia "made it up as he went along"]]. Subverted when Episodes 1-3 were remade shortly after, wherein they made sure to foreshadow it. See the ChekhovsGag entry for what in the episode ''was'' planned ahead.* BadassDecay:** Giroro. Flashbacks makes him nauseous, and he is [[{{Irony}} allergic to cats]]. Episode 17 also revealed that [[spoiler:he never properly learned how to shoot a gun and never finished military training, evidenced by his failure to land a single shot on Garuru]].** Invoked with Zoruru, and after only one scene. His first appearance has him [[spoiler:[[KnightOfCerebus kill Koyuki]]]] immediately following a PreMortemOneLiner. His second appearance has him getting a disruptive Skype call from his mom, followed by excessive paranoia about how Natsumi must want to start dating him.* BigLippedAlligatorMoment:** Todd Sirkowski of ''Todd's Toilets'' flying by in a hot air balloon and immediately crashing/exploding. Three times. Eventually subverted when Aki shows up and hints that this thing has happened before.** ''Mint's Hints'' from Episode 8 [[SubvertedTrope was one until]] Tororo brought it back for Episode 17.** "Keroro Love Fighters, commencing attack!"* CrossesTheLineTwice: The games Keroro and Giroro played with Zeroro: "Zeroro Dies" "Zeroro Plays Chicken With a Bullet Train", "Zeroro Hides-and-We-Take-His-Stuff-Seek".* EnsembleDarkhorse:** Dororo was this at the start of the series. Yoshi didn't even ''want him in the series'' before his first appearance, but he became the one character who developed the most over time. When the series ended after Season 2,[[note]]Thorn brought it back a few months later[[/note]] he was voted Travis, Yoshi and Thorn's favourite character.** Tororo got a massive wave of praise after Episode 17. It could have been because Tororo has a large fanbase already, or simply because Travis did ''that'' good a job.** Practically every non-recurring character became one, including Asami, Grandpa Viper, the animators, Joriri, Pururu, and the "teeth guys". Yoshi often lamented that these characters did not show up more often, since he loved how they came out.* FunnyAneurysmMoment:** In Episode 15 Fuyuki randomly says he no longer believes in God. The line, though otherwise unconnected, was written around the time of Creator/ChristopherHitchens' death.** Saburo's original voice actor [=DFatman=] intended to voice him as a drunk. When Fatman was kicked out of the team, Thorn and Yoshi decided to leave Saburo mute for RuleOfFunny, until Episode 18 when he was very briefly voiced by [=MrFailGame=]... who later died from alcohol-related problems.* HarsherInHindsight: In ''SFA: Reset'', Keroro notes that [[CharacterDevelopment his attitude has changed]] after having "a rough talk with a friend", the exact thing that would end Thorn and Yoshi's working relationship a year later.* HilariousInHindsight: The writers made all of the characters [[EveryoneIsBi defaulted to bisexual]] unless stated otherwise, and Giroro was also made a WholesomeCrossdresser. Writer [=ThornBrain=] came out during production of Episode 11 as a bisexual transvestite, which he was only starting to realize around the time Giroro was made a crossdresser.* HoYay:** The series made Keroro and Tamama a couple. [[spoiler:Subverted after Episode 10, when it is discovered that Tamama is actually a girl]].** Giroro and Dororo. Dororo actually hit on Giroro at the end of Episode 6, they have a semi-serious bit of bonding at the end of Episode 7, and they are noticeably closer friends by Episode 11. Then in the Post-Credits to Episode 14, [[spoiler:Dororo asks Giroro to marry him]]. [[spoiler:And then ''TheyDo'' get married in Episode 15. Giroro even says "We've been fucking behind your backs for ''months!''"]]* GrowingTheBeard: Though they don't count it among the series' best, Thorn and Yoshi consider Episode 4 to be the point where everything in terms of writing and voicing started to gel, be it due to the expulsion of previous redundant team members or simply the introduction of [[BreakoutCharacter Dororo]]. Yoshi also didn't pick up as a voice-actor until Episode 4, nor did he enjoy voice acting until then.* LGBTFanbase: Thanks to a more nuanced approach to various sexualities in the characters and not reducing any of them to QueerPeopleAreFunny jokes.* MemeticMutation: "[[http://www.youtube.com/watch?v=xsCu5tdUSoU What's your opinion on paper mache?]]", shared with ''WebVideo/JettersAbridged''.* RescuedFromTheScrappyHeap: Many Manga/SgtFrog fans dislike [[YMMV/SgtFrog Joriri and Pururu]], but their [=SFA=] reinterpretations got a lot of love from those same fans.* SeasonalRot:** [[CreatorBacklash Writer Thorn considers Episode 13 to be the series' low-point]], and although the episodes after were fine, he thinks Episode 17 was when SFA finally dug back out of it and truly get its spark back. This was mainly due to him and Yoshi jumping ahead and planning for 17, and the resulting excitement for such a later episode left them with no ideas or motivation for 13. It took them three tries to find an episode they could work with, and the resulting script was dry and unimpressive. Yoshi and Travis generally agree that 13 was "kinda bad", whereas all three (and many viewers) agree that 17 was one of the series' best episodes.** Earlier, bringing Travis in to help write Episode 9 was Thorn [[DefiedTrope attempting to prevent this trope]] after a particularly idea-less Episode 8. Episode 10 was also written with a back-to-basics approach after Thorn realized that Episodes 8 and 9's biggest flaw was that they were too self-aware.* SomeAnvilsNeedToBeDropped: Episode 11's "[[NoBisexuals It's okay]] [[BiTheWay to like both]] [[EveryoneIsBi men and women]]".* TearJerker: Fuyuki's speech to a brainwashed Keroro in the finale:-->'''Fuyuki''': "You're right, Keroro. It is funny. Somehow you managed to turn everything that happened [[NeverMyFault into everyone else's fault.]] You ever think about why you can't make people happy? Because nothing you've done in your ''entire'' life has been for anyone else. You hurt my sister for questioning you, you abandon Tamama for being herself, you take advantage of [[TeamMom Giroro for keeping the team together,]] you mock Dororo for his undying devotion to you... and tell me, Keroro... [[ArmorPiercingQuestion Did you ever once think of what I go through to protect you!?]] (Crying) You donít care about anyone... You just drag everyone through the dirt... Now everyone who ever cared about you ''hates'' you... But it didnít matter to me. You were my friend, [[FriendlessBackground the only real friend I ever had]]. I took everything you gave us... ícause I wanted you to be happy. Does that mean a ''[[PrecisionFStrike fucking]]'' thing to you?!"* ViewerGenderConfusion: In and out-of-series. [[spoiler:Even Tamama didn't know she was a girl.]]** This actually came about as a result of ''Writer'' Gender Confusion: for the first several months of the team's existence, Thorn kept thinking Tamama was a girl. By Episode 3, [[spoiler:he and Yoshi just decided to make it that way]].* TheWoobie:** Dororo, [[HilariouslyAbusiveChildhood especially as a child]].** Lil' Pururu hints that her mother is a violent drunk.--->"When my mommy drinks juice, nobody's happy."----
